Aponogeton ranunculiflorus

A tiny alpine aquatic from the Lesotho highlands that grows from a pea-sized corm in sandstone rock pools, tarns and mires, floating its leaves and white flowers on the surface. It needs cool, sunny summers and a cold winter rest in which the pools may dry or freeze; it is endangered and rarely grown.

Where it grows wild

Permanent and seasonal sandstone rock pools, tarns and high-altitude mires on the Drakensberg-Maloti plateau, fully exposed to sun. Spiral stems keep the flowers at the surface even in deeper pools, and the small corms survive pools drying out or freezing into the mud.

Measured records sit at 2439 to 2600 m; the literature gives 2600 to 3200 m.
